Abstract

1493619 Purification of chlorinated solvents PPG INDUSTRIES Inc 11 Dec 1974 [11 Dec 1973] 53530/74 Heading C2C [Also in Divisions B1 C5 and D1] Minor concentrations of hydrogen peroxide are removed from liquid chlorinated drycleaning solvents by contacting an insoluble, particulate, cross-linked ion-exchange resin containing a strong base, weak base, strong acid or weak acid functionality with said solvent containing hydrogen peroxide until said solvent has a lower hydrogen peroxide concentration. The solvent may be perchloroethylene, trichloroethylene, methylchloroform, 1,1,2-trichlorotri. fluoroethane or dichlorodifluoromethane. The resin may be regenerated by washing with water.
